LATERALLY-ADJUSTABLE TABLE FOR AUTOMATIC PAPER-SHEET FEEDEBS.

Application filed June 7,

provide an improved feed table or hopper which may be bodily adjustedacross the machine, so that the side guides may be adjusted for thewidth of the sheet to be fed and then the entire mechanism adjustedproperly with the rest of the machine.

Another object is to provide a laterally adjustable feed table or hopperfor automatic feeders that will permit the running of the small stocknear one edge of the feed table and the operator have easy access to thetable from the side without the necessity of reaching over from the rearof the table;

A further object is to provide a locking means for securing the feedtable or hopper in the required position.

A further object is to provide a simplified form of'construction whichshall be rigid and yet of light weight and simple to manufacture.

Other objects of the invention will appear from the following detaileddescription.

The invention consists generally in various constructions andcombinations, all as hereinafter described and particularly pointed outin the claims.

Inthe accompanying drawings, forming a part of this specification, 1igure 1 is a plan View of an automatic folding box gluing machine withmy invention applied thereto, showing the machine set up for a mediumsized blank with the edges of the blank engaging suitable guides placedon the lefthand side of the feed table or feed hopper.

F igure 2 is a View similar to Figure 1 except that the machine is-setup for a narrower blank with the edges of the blank guided by settingthe guides close to the left-hand side of the feed table and the feedtable adjusted laterally to the right, so that the operator may stand onthe side and easily supply the hopper with the small blanks without thegreat inconvenience of reaclnng over f om the back of the feed table tothe feed wheels, a distance of about 32 inches.

1926. Serial No. 114,216.

' Figure 3 is a side view of the feeder lookmg from the drive pulleyside of the machine.

Figure 4 is a section through the center of the feeder.

Figure 5 is a detail of the feeder showin the left side bracket and itsmanner 0% mounting, so that it will slide laterally on the uides.

Figure 6 is a rear view of the feeder with i the feed table or hopperremoved, toshow the manner of mounting the supporting brackets for thefeed table.

Figure 7 is a view similar to Figure 6, except that the brackets whichsupport the feed table are shown at the limit of adjustment.

In the drawing, 2 represents a folding paper box gluing machine havingthe usual drive pulley 3, glue pot 4, delivery table 5, the lower feeddrum 6,-having the usual carrier belts 7 and feed wheels 8, all mountedupon suitable shafts and driven in a suitable manner.

The feed wheels 8 are preferably mounted on a shaft 9 having hearings inbrackets 10 and 11 on each side of the machine.

This shaft 9 is usually driven by the feed wheels through theirfrictional contact with the belt 7.

The brackets 10 and 11 are connected with each other by a shaft 12,having an extension 13, and a shaft 14, having an extension 15. (SeeFigures 6 and 7.)

The shaft 14 has akeyway 16 and supports the feed adjusting mechanism17, each being secured in position after once heing set by the small setscrew 18, which bears rigidly, and the two brackets are secured inposition by the cap screw 23, which clamps the upper part of the bracket21 on to the extended portion 13 of the shaft 12.

To the bracket 19 I pivot an arm 24 at the point 25, and to the bracket21, I pivot an arm 26 at the point 27 i Suitable dogs 28 adapted toengage the teeth 29 in the brackets 19 and 21 are provided for holdingthe arms 2& and 26 in their adjusted positions.

The arms 24 and 26 are connected with each other by suitable boards 30,31 and 32. The boards are spaced apart at points 33 and 34, so thatsuitable guides 35 may be placed on the upper side of the board andadjusted in the slots or spaces between the boards across the machineand clamped into position by the hand wheels 36 and 37.

In operating a machine equipped with my invention, the operator adjuststhe machine as in my patent above referred to, but in-. stead ofstanding at the rear of the machine and reaching a distance of 32 inchesto feed and keep the action of the feed wheel 8 under constantobservation, as well as lifting the rear of the stack so that a new liftma be fanned out and inserted under the stact from which the feed wheel8 is feeding, he simply'adjusts the side guides to the lefthand side ofthe feed table and moves the table towards the right in line with thepath' of the blank through the machine and stands ,on the left-hand sideof the feed table, where he has easy access to the feed table, as wellas immediate contact with the starting and stopping levers, the gluecontrol levers, etc.,

which, except for my invention would require his passing around to theside of the machine. e

After setting the machine and moving the feed table to the rightposition, as shown for instance in Figure 2, the operator takes a wrenchand tightens the screw 23, locking the feed table against lateralmovement, and the angle or pitch of the feed table is then adjusted bythe action of the ratchet dogs 28 in the notches 29 of the brackets .19and 21.

It usually happens that after the machine is set up, the folding isinaccurate and the folder frames will have to be either opened or closedto a greater degree. Therefore the re-setting of both feed guides 35would be necessary unless the machine was equipped with this invention.

If it is so equipped it is merely a question of loosening the cap screw23 and tapping the feed table with the palm of the hand slightly ineither direction to make it line up with the rest of the machine, sothat the blank may enter the feed wheel at the pro er point for the glueflap to pass over the glue i wheel and the creases on the folding box tocome in the right position for the folding mechanism.

I claim as my invention:

1. The combination with a frame and feed wheels mounted therein andmeans for driv ing said wheels, of brackets mounted for 2. In a machineof the class described, tilting arms mounted for lateral adjustment, a

feed table supported by said arms and comprising plates spaced apart toform gaps extending transversely of the table, upri ht guides mounted onsaid table and adjusta le transversely thereof and having means forsecuring them in'said gaps, the adjustment of said guides adapting saidtable for receiving and feeding blanks of different widths.

3.
